Case Number : Case 2390 - 28 August 2019 Posted By: Dr. Hafeez Diwan

?Bcillary Angiomatosis.

Clinically, the suspicion was of polyarteritis nodosa.  There is vascular necrosis with lymphocytes and thrombi in the subcutaneous fat.  So I called it vasculitis and considered lymphocytic thrombophilic artertitis,

I also thought of PAN, which may manifest as thrombosis of small vessels or thrombophilic arteritis (considered as indolent variant of PAN). The reticulate pigmentation and subcutaneous nodules are congruent with cutaneous PAN. I was confused for crusted papules- ?is this clinical morphology unusual for PAN or is it known.
